Filed: 1987-10-16
Abstract: PURPOSE:To reduce the number of times of key input and to efficiently input data by providing a fraction part preferential input means, an integer part preferential input means, and a selecting means which alternatively validates both means. CONSTITUTION:A CPU 1 judges whether a host currency unit preferential input system (the integer part preferential input means) or a subordinate currency unit preferential input system (the fraction part preferential input means) is set. In the former case, the numerical value already inputted to a memory 2 is shifted up by one digit and an inputted numerical value is displayed at the least significant digit if a decimal point input flag is set. In the latter case, the inputted value is entered to the least significant digit and the whole of the already inputted numerical value is shifted up when an enter key is inputted from a keyboard 5. Thus, the number of times of key input is reduced and data is efficiently inputted because the input of a fraction part is omitted when numerical data of only the integer part is inputted. Further, the fraction part preferential input means is provided to use this device in accordance with purposes.
